Chess is played by two people, one with white and the other with black. The chessboard is square, consisting of 64 small squares, 8 squares in vertical and horizontal directions, and the colors are interlaced with each other. Dark squares are called Haig, and bright squares are called white squares. Chess pieces move in these squares, and the lower right corner of each player is a white square.

Eight vertical grids are represented by lowercase letters A, B, C, D, E, F, G and H respectively. The eight bars are represented by the numbers 1, 2, 3, 4, 5, 6, 7 and 8 respectively. In this way, the coordinates of each grid can be identified by letters and numbers. Each work and the layout of the work. A total of 32 pieces were divided into black and white groups, with one piece in each group and 16 pieces in each group.

Chess consists of black and white pieces. Whether it is a white field of vision or a black field of vision, the lower right corner of the board must be white, the white must be placed on top of the white, and the black must be placed on top of Haig. White King is in e 1 grid, and Nidhogg is in e8 grid.

The game is played by the white side first, and both sides take turns to move the existing pieces on the chessboard. You can only move one piece at a time. Chess pieces either move to an unoccupied chess box or occupy the chess box where the opponent's chess piece is located, and the opponent's chess piece is taken out of the chessboard, which is called "eating".
